ABSTRACT:
An accumulator type, rechargeable atomizing mechanism having a container for liquid to be atomized, an atomizer body, and atomizer head and an engaging member having a large-diameter hollow cylindrical portion. The atomizer head cooperates with skirt-like small and large diameter pistons formed on a piston member. The large-diameter cylindrical portion of the engaging member is held within the peripheral wall of the atomizer head and is formed with a rod portion extending downwardly from the large-diameter cylindrical portion. The atomizer body is formed with a lower, small-diameter cylindrical portion. The large-diameter piston is held by the large-diameter cylindrical portion of the engaging member and the small-diameter piston is held by the small-diameter portion of the atomizer body. A longitudinal recess is formed on an upper, large-diameter cylindrical guide portion of the atomizer body, and a hole is perforated at the junction between the upper and lower cylindrical portions of the atomizer body. A longitudinal slot is formed on the upper portion of a rod-like valve which extends downwardly from the rod portion of the engaging member. When the valve body reaches its lowermost position, this longitudinal slot communicates the interior of an accumulator chamber (formed by the piston member and the engaging member) with a passage which is connected to a suction tube extending from the liquid to be atomized. This operates to release residual pressure from the accumulator chamber into the suction passage and prevents a residual pressure from opacifying liquid in the container.
